Be it known that I, FRANK E. C1201, a c1t1- STATES P E T FFI E FRANK E. error, or WATAUGA, Tennessee.

zen ofthe United States, residing atW-atauga," in the county of Carter and State of 1 Tennessee, have invented certain'new and useful Improvements in Sash-Locks; and I l do hereby declarethe following to be-a full, clear, and exact description of the invention,

such as will enable others skilled inthe art to which it appertains to make and use the same.-

This invention relates to improvements in sashlocks.

The object of thisinvention is the Provision of a novel lock, which isadaptedto be i I appliedto window frames ofthe usual construc'tion and so arranged asto be partially concealed, from view and adapted toengage theupper and lower sash within the window frame to holdthesameagainst movement in one direction. p v, further object of this inventionis the provision of "a sash lock of this character,

which is provided with novel means whereby [a pair of'pivoted pawls may be adjusted to fit various size window frames, so that i one pawl may engage the upper sash and one .p'awlthe lower sash and means for holding the pawls into engagement with the sashes, thus permitting the sashes to be .moved in only one direction, until the pawls arelreleased. v r A still further object. of this invention is v the provision of a. sash lock which is provided with a novel'means which is located on the inner side of one side of a window frame,so that the dogs which engage the rackbars carried by the s ashes may be re- 1 leased to permit the sashes to be moved in either direction. I

A still further objectof this invention is u 1 the provision of a sash lock which is adapted to be secured to one side of a window frame, on. the inner side'thereof andlocated in the weightchamber and isfconstructed-of suita able materialembodying a socket which is journaled totherouter sid'esof thesides'of ,1-thewiudow frame and a horizontal shaft havingone end journaled in thesocket. and r itsfopposite' end extending through the inner sidesqof the" sides of the window frame, a dfflla'tch. arran ed on said'ishafgpawls'jour- ,naled-onsaid shaftand arranged to extend hereto appended.

Like numerals of reference designate corresponding parts in allthe figures of the drawings.

Referring more-particularly tothe'draw-u I ings,-thenumeral 1 designatesa window. frame of the usual construction having the 1 sides 2 and ends 3. The sides2 definethe usualweight receiving compartments which areattachedtothe sashes, so that'thesame 3 iv may be easily raised and-lowered. Secured inthe window frame is theupper sash t and are provided on their outer faces with teeth 10 and the teeth on the upper sash are inclined" downwardly while the teeth on the lower sash are inclined upwardly, the purpose of which will be hereinafter more fully described. The side rails 2 are provided with slots 11, which slots are located near the center of the side rails 2 and extend horizontally through theside rails 2 and communicate with the weight receiving compartments therein.

The slots 11 are offset with relation to one,

another and one slot is located in the groove in which the lower sash 5 slides and the other slot is located the groove in which the upper sash 4 slides. The slot which is located in the groovein which the upper sash slides is in superposed relation to the slot which is located in the groove in which the lower sash'slides. The inner Wall of each of the slots is inclined as at 12, so as to permit the pawls to readily move into active position.

The sides 2 are provided with the outer strips 13 and inner strips l4, which form the weight casing. A socket 14' is provided at one end with an attaching flange 15, which is secured to the inner side of one of the outer members 13 and the socket is arranged in a horizontal plane and extends in the direction of the inner member 14. The inner member 14 is provided with an opening 16, which is in direct alinement with the bore 17 in the socket member 14. The opening 16 terminates into a rectangular recess 18 which is located on the outer side of the inner member 14 so as to be located on the interior of a room in which the window frame is located.

taching flanges 21, which are provided with openings 22 adapted to receive fastening elements 23 for securing the bearing bracket to the inner side of the side2 and intermediate the members 13 and 14. The bracket 20 is provided with a horizontal opening '24,

which opening is in alinement with the bore 17 of the socket 14 and the opening 16 in the member l l.

A shaft 25 is extended through the opening 16 in the side member 14 and through the opening in the bracket 20 and has its inner end journaled or rotatably mounted in the bore 17 of the socket 14, the outer end of the shaft projecting beyond the side member 14.

' The shaft 25 is provided with a plurality,

of inwardly extending openings 26, which openings are arranged at a s aced distance apart so as to permit a pin 27 tobe removably arranged therein, the purpose of which will be hereinafter more-fully described.

A pair of arcuate pawls 28 have one end enlarged as at 29, and the enlarged ends are substantially circular and provided with openings 30 to receive the shaft 25. The opposite ends of the pawls 28 taper to a point 31 and are adapted to extend through the slots 11 for engagement with the rack bars 10 carried by the upper and lower sashes for holding the upper and lower sashes against movement in one direction. The pawls 28 are keyed to the shaft 25 and extend in opposite directions and are arranged on' opposite sides of the bracket 20, as clearly shown in Fig. 2 of the drawings.

Thepawl'28 which is arranged to engage the lower sash 5 has formed from its circular inner end a vertical projection 31, which is adapted to extend upwardly beyond'the ranged on the outer side of each of the pawls are located intermediate the opposite side longitudinal edges of the pawls and are adapted to receive therein one end of the 'spring'arms 35, which spring arms have their inner ends, connected to the horizontal body portion 36. The horizontal body'portion 36 and spring arms 35 are all formed of af singl'e piece of wire and the arms are formed on the opposite ends ofthe horizontal bodyportion extend inopposite directions and arranged to be seated in the grooves 34, so as to normally urge thepawls outwardly through the slots 11' the side 2 of the window frame.

A bell crank lever 38 1S pivota'lly secured upon the horizontal ,shoulder 32 of the bracket 20 as at 39 and has one arm arranged to en 28. The opposite arm of the bell crank lever '38 is provided adjacent its end with an opening 40 and is adapted to be pivotally secured to the upper pawl 28 by. a link- 41, which is connected to a staple 42 carried by the upper pawl 28 so that upon move-v v mentofthe shaft in one-direction, the lower a pawl will be moved inwardly against the tension ofthe spring arm 35, thus moving its vertical portion into engagement with the arm 43of the bell crank lever, moving the same on its pivotal point 39, thus pull- 1 ing the upper arm 28 out of engagement ber 14, is bi f ao with the rack teeth 10 of the upper sash I member simultaneously.

which engages the outer sideof the member to limitv the inward movement of the keeper 46 within the recess 18.

The keeper plate 46 is. provided with an opening 48 through which the outer end of p the shaft 25 extends.

The flange 47 of the keeper plate 46 is secured to the member 14 by suitable rivets, screws or the like designated 49 so as to hold the same in position within the recess 18' and prevent accidental displacement therefrom.

A'latch 50 is provided with a shank 51 which is pivotally mounted between the arms 45, defined by the bifurcating of the outer end of the shaft 25. The shank 51 is pivotally secured therein by a pin 52, so as to permit the latch 50 to be swung upwardly and positioned within the keeper plate 46. Thekeeper plate 46 and latch 50 are provided with thumb slots 53, which permit the latch 50 to be moved outwardly in a horizontal 'planefor rotating the shaft for moving-the pawls 28 out ofengagement with the teeth 10carried by the upper and. lower sashes 4 and 5, which are located within the 7 ous widthsof the side 2 of the window frame, and the shaft and dogs or pawls arewindow frame 1.
